"I'm not an artist who has ideas. I hate ideas. And if I have one anyway, I go for a walk to forget it. I need the uncertainty, the not knowing. It's actually like a performance, you don't know exactly what's going to happen beforehand. So, at best I'm a blank slate when I go into the studio. Unfortunately, I'm often a blank slate when I go out, too."
Robert Rauschenberg (1925-2008)
